I am trying to make a basic drop down forum which when options are selected they will load a URL on a submit button click.
我想要这样的东西
下拉一个
自行车品牌:KTM BMW Ect
自行车型号:(如果上面选择了 ktm 会显示)990 EXC Ect
(如果上面选择的宝马会显示)GS Adventure Ect
因此,如果自行车的品牌是 ktm 并且型号是 990,点击提交按钮将加载 Www.website.com/ktm/990
这是我拥有的代码,我已经对拣选部分进行了排序,所以如果您选择 KTM,它会向您显示 KTM 的型号,并且与 BMW 相同,唯一的问题是我根本无法让 URL 正常工作并且不知道该怎么做它。
<script language="javascript" type="text/javascript">
<!--
function setOptions(chosen) {
var selbox = document.myform.model;
selbox.options.length = 0;
if (chosen == " ") {
selbox.options[selbox.options.length] = new Option('Please select one of the options above first',' ');
}
if (chosen == "BMW") {
selbox.options[selbox.options.length] = new
Option('R1200-GS-Adventure','R1200-GS-Adventure');
selbox.options[selbox.options.length] = new
Option('R1200-GS','R1200-GS');
selbox.options[selbox.options.length] = new

selbox.options[selbox.options.length] = new

}
}
